Gamma Polyglutamic Acid (γ-PGA) is a natural, multi-functional, biodegradable biopolymer produced from L-glutamic acid through a fermentation process with a Bacillus subtilis. PGA is a water-soluble homo-polyamide consisting of D- and L-glutamic acid monomers connected by amide linkages between α-amino and γ-carboxyl groups. It has high water absorbability and moisturizing effect with multiple functionalities including Long-lasting moisturizing effect and inhibition on Melanin Biosynthesis.It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.

Applications:γ -PGA and its derivatives have molecular weights ranging from 50, 000 to more than 2 million Daltons, hence they have wide applications in food industry, cosmetics, health care, water treatment, waste water treatment, Hygiene products, Medical treatments, Hydrogels etc.
